Another question might be “Can you afford not to have a cross direction coat weight or moisture measurement?”
Process Sensors Guardian Nova Series of Cross Direction Web Profile Systems are designed to encourage early entry into the measurement and control of the web profile.
Our PC based Guardian Cross Direction Web Profile System is the work horse of the industry. Fast, accurate, reliable, Ethernet communications, analog outputs, remote on-line diagnostics and Easy-to-Operate, the Guardian is an established brand in the industry.
What if you’re a new or expanding company that doesn’t have a lot of capital? You get a new or bigger contract re-newel. Normal procedure requires start up, samples sent to lab, 20 minute response at best, make adjustments, new lab sample for confirmation and operation at best. Contract is great but the time to get to set point is more critical and impacts production volume. Also, if there’s a wedge or edge splurge that messes up profile, it messes up roll delivered to customer. A complete cross direction web profile system pays for itself quickly.
Guardian opportunities now include a simple scanner, transmitter and digital display. The basic system does not include a cross direction web profile. It provides a digital measurement of coat weight or moisture across the web. It can be programmed for automatic scanning or to machine direction lane with trend plot. If you spot a problem, you can locate it, adjust the nip pressure, dye bolt, skew, or whatever is needed and immediately see the result to obtain a uniform profile. This is especially important on start up. It allows emerging or budget restricted companies a quick way to provide their production operators a tool for process control.
Measuring moisture or coat weight, film thickness or PSA Cross Direction Web Profile speeds start up, reduces out-of-spec product and increases profits.
The Guardian 12” Operator Interface System offers the same features as the basic system with a complete Cross Direction Web Profile. No data logging, but it offers a quick, accurate and easy-to-operate system to optimize start up and detect problems. Ideal for lowering start up time and increasing production for emerging companies.
PC Based System can communicate with an HMI (Human Machine Interface) meaning that the operator can simply change a roll or customer order via the HMI and that activates appropriate product and historical codes automatically. Multiple scanners, transmitters and measurements such as coat weight and residual moisture!
